[LLVMdev] ARM interrupt attributes (IRQ and FIQ) support
Hello, As part of a try to make clang/llvm build Rockbox, we realized that clang and llvm have no support for irq/fiq calling convention on ARM which is implemented using the interrupt("IRQ") and interrupt("FIQ") attributes on GCC. Although it is always possible to implement those in assembly, I would like to know if there has been some work done to implement this the same way GCC does, or if there is no plan to support this in future ? I am no llvm expert but with some help I think I could implement this if it is a wanted feature. Thanks, Amaury Pouly -------------- next part -------------- An HTML attachment was scrubbed...
